There is a 2-week break in between phases during which patients do not receive any medication. The trial is closely monitored for safety.

Who is the study for?
This trial is for Type II diabetics who've had chronic constipation for at least 6 months, with hard or lumpy stools.

What is being tested?
The study tests Linaclotide against a placebo in people with diabetes and chronic constipation over two phases of 14 days each, separated by a two-week break. Participants are randomly assigned to start with either the active drug or placebo and then switch after the break.
